pumps, compressors, etc.) is used. Flickers display a cluster of bars, one for each phase.
The color of each bar indicates the compliance status for each phase. A green bar
indicates that the parameter is within compliance. A red bar indicates that the parameter
does not comply with EN50160.
Supply Voltage Unbalance: The unbalance of a three phase supply voltage consists of a
loss of symmetry of the phase voltage vectors (magnitude and/or angle), created mainly
by unbalanced load. Compliance is verified when 95% of the sequence of valid 10
minute values are within the specified tolerance of normally 2% (in single phase/two
phase supplies 3%). Supply Voltage Unbalance is represented by a single value and a
single bar. The color of the bar indicates the compliance status for each phase. A green
bar indicates that the parameter is within compliance. A red bar indicates that the
parameter does not comply with EN50160.
Harmonic Voltage: Harmonic displays a cluster of bars, one for each phase. The color
of each bar indicates the compliance status that is calculated by adding the status of
Total Harmonic Distortion (THD) and Harmonics 2 thru 25. The bars for Harmonic
Voltage is a hyperlink to the Harmonic graph (see page 8-8).
Interharmonic Voltage: Interharmonic displays a cluster of bars, one for each phase.
The color of each bar indicates the compliance status that is calculated by adding the
status of Total Interharmonic Distortion (TID) and Interharmonics 2 thru 25. The bars
for Interharmonic Voltage is a hyperlink to the Interharmonic graph (see page 8-8).
Mains Signalling: Mains Signalling is represented by a single value and a single bar.
The color of the bar indicates compliance status that is calculated by adding the status
of each of the defined frequencies (a maximum of five) for its phase. Users can specify
the signalling frequency values under Advanced Options (see Chapter 6 Advanced
Setup Options - EN50160 Power Quality on pages 6-20 to 6-21). A green bar indicates
that the parameter is within compliance. A red bar indicates that the parameter does not
comply with EN50160.
